That's a good point; OTOH, I like the conceptual grouping of `system- foo`. Doesn't your completion let you type, e.g., #\s #- #\c [complete] to get the symbol? After all, sense `compile` and `load` are already CL symbols, you'd need to type #\l #\o #\a #\d #- [complete] or #\l #- #\s [complete] in any case.
except with fuzzy completion that scores consecutive matching characters exponentially, so typing 'load' brings up both versions on the top wherever 'load' is in them...
but i still prefer load-system because in english you would say 'load the/a system' not the other way around.
